We divide 858545 by 80
Our goal is to divide 858545 by 80.

On to step 1:
8 divided by 80 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 80

Going ahead to step 2:
The number 80 fits into 85 1 times, leaving a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 80 from 85 to get 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 80

Step 3:
80 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 58 leaves us with 58.
Include the next digit (5) from the dividend after 58, then repeat: 585 / 80

Let's proceed to step 4:
The number 80 fits into 585 7 times, leaving a remainder of 25.
The next digit of our result is 7. 
Result so far: 107.0
Subtracting 560 from 585 leaves us with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 80

Advancing to step 5:
80 can be fit into 254 3 times, resulting in a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 1073.0
Deduct 240 from 254 and we're left with 14.
Include the next digit (5) from the dividend after 14, then repeat: 145 / 80

Moving on to step 6:
80 goes into 145 1 times with a remainder of 65.
Put 1 as the next digit of the answer. 
Result so far: 10731.0
Deduct 80 from 145 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
The number 80 fits into 650 8 times, leaving a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 10731.8
If we take 640 away from 650, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
80 can be fit into 100 1 times, resulting in a remainder of 20.
The next digit of our result is 1. 
Result so far: 10731.81
If we take 80 away from 100, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 10731.812
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 10731.8125
Subtracting 400 from 400 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
When dividing 0 by 80, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10731.8125
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10731.8125
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 10731.8125, and the remainder is 0.0.
